Extreme X-ray Behavior in the Low-Luminosity Active Nucleus of NGC 4395
E. C. Moran, M. Eracleous, K. M. Leighly +4
We present the results of a 17 ks Chandra observation of the nearby dwarf spiral galaxy NGC 4395, focusing on the X-ray properties of the moderate-mass black hole that resides in i…
Measuring Black Hole Masses Using Ionized Gas Kinematics
Aaron J. Barth, Marc Sarzi, Luis C. Ho +5
We describe techniques for measuring the central masses of galaxies using emission-line kinematics observed with the Hubble Space Telescope. For accurate results, it is necessary t…
Nonstandard Central Engines in Nearby Galaxies
Luis C. Ho
We argue that nearby galaxy nuclei contain massive black holes that are fueled by low radiative efficiency accretion flows.
The Population of AGNs in Nearby Galaxies
Luis C. Ho
This contribution reviews the properties of nuclear activity in nearby galaxies, with emphasis on results obtained from current optical surveys and multiwavelength follow-up observ…
The Central Regions of Early-Type Galaxies Hosting Active Galactic Nuclei as Viewed with HST/NICMOS
Swara Ravindranath, Luis C. Ho, Chien Y. Peng +2
We present preliminary results from surface photometry of a sample of early-type galaxies observed with NICMOS on board HST in the F160W (H-band) filter. Dust is found to occur mos…
